• Visual Studio how can I disable the debugger?

  Every time a program crashes or do something wrong it pops up a window that ask me what debugger I want to use. Its annoying... I causes me to exit from this game I'm playing - "Titan Quest" and I don't want it to pop up anymore... I am in the same situation, I am sick to death of it popping up everytime a program chucks the slighest error. Surely there must be a simple way to turn it off. ...Show All

• Windows Forms hyperlink in datagridview

  I'm using a GridView in C#.Net 2005. One of the column of the GridView is Hyperlink Column. When i click the hyperlink i want some message to be displayed in another datagridview page and that should be retreived from database based on the link message. i know how to put the hyperlink to the text,but i dont konw how to retreive information based on that link. How can i achieve this Where should i write my coding Hi Shirisha, I assume you must have used DataGridViewLinkColumn to display your HyperLinks. In that case, in order to repspond to User Clicks on HyperLinks, you must handle the CellContentClick event. This event is distinct from the CellClick and CellMouseClick events, which occur when a user clicks anywhere in a ...Show All

• Software Development for Windows Vista How can I get Workflow Status from Tracking DB without using SqlTracking and WorkflowStatus?

  How can I get Workflow Status from Tracking DB without using SqlTracking and WorkflowStatus property, but by select  statement from DB I'm not sure I fully understand your question but I'll take a shot at a possible answer. There is no single column that holds a current status so you need to compute it. Computing it can be done a couple of different ways depending on how you define status and what you want to show. For example you could just get the most recent record for the instance from the vw_WorkflowInstanceEvent table. Join to vw_TrackingWorkflowEvent on TrackingWorkflowEventId to get the text description of the event. You could say that if the table doesn't contain a value for Completed or Ter ...Show All

• SQL Server long running packages

  I need to execute a long running package (it takes about 16 hours to finish) to load a data warehouse for the first time with all historical data. This package it's a master package and execute other packages; I log the start time and the finish time of the package in a table to manage future incremental loads.

• Software Development for Windows Vista WinForm IN ActivityDesigner

• Visual Studio MSI Deployment Issues

  I've successfully created my TemplateSetup.msi file. However, when installing my template from the setup.msi file, I get a popup stating: The file aAlpha.config could not be foundwithin the project templates. Continuing to run, but the resulting project may not build properly. This file is in a folder called Config. The folder is copied over successfully but aAlpha and the other config files located in that folder all pop up the same error message. I have config files located in the root of the website and they are also giving the same pop up message of not being found. I also get the message for my MyMaster.Master page, but the MyMaster.master.vb file is copied over without any issues. Does anyone know why this would be hap ...Show All

• Visual Studio Express Editions displaying the value of a particular database field

  First let me say that, as you might guess, I do not have much experience with Visual Basic. I have a database with 50 records (rows) and 35 fields (columns). My program calculates a value from a bunch of other input information and based on that value the correct field name is assigned to a variable. The records are bound to and listed in a combobox (that part works fine). When I select one of these records I want to assign the corresponding value, from the field that is specified by the variable, into another variable. Does that make sense and if it does - does anyone have any suggestions. Thanks to both of you. Sometimes I think it is the simple stuff I get hung up on. I have worked around this pr ...Show All

• Windows Forms Force property grid to completely refresh.

  I've implemented dynamic type information for a control class using ICustomTypeDescriptor. Specifically, setting one property to a certain value causes some other properties to become irrelevant so I omit them from the properties collection in ICustomTypeDescriptor.GetProperties(). The problem is that the PropertyGrid control that is displaying the properties for the object does not update to show these changes, even after calling Refresh() on it. I've also tried doing stuff like clearing the selected object from the property grid and re-setting it but it still shows the old set of properties. One strange thing is that resizing the control by dragging one of the resize handles causes the grid to update properly (setting the size via ...Show All
